Evaluation of the Possibility of Use Geothermal Energy Micropiles TITAN 73/53 to Obtain Low-Temperature Heat Energy Accumulated in the Near-Surface Layers of the Ground in Poland Area

Increasing demand in the usage of low-temperature energy sources such as atmospheric air, ground, groundwater or wastewater, which are freely available in the environment, lead to seek new methods and technologies to obtain them. One of these are for example geothermal energy piles (GEP), foundation piles inside which a vertical exchanger is placed to exploit low-temperature geothermal energy. They gained growing popularity over past few years, because of modern assembly technology which allows to make them in any conditions during one technological process. The aim of the work was to estimate the possibility of use geothermal energy micropiles TITAN 73/53 to obtain low-enthalpy heat energy from near-surface layers of the ground in Poland area. Assessment was carried out based on Map of Geological-Engineering of Poland on a scale of 1:500,000, enriched with information gained from literature data and from TITAN Polska Company. Conducted analysis has shown that geothermal energy micropiles TITAN 73/53 in the most parts of the country can be used as very promising and cost-effective technology for more efficient, even 50% more than conventional, acquisition of relatively large amounts of heat energy accumulated in shallow layers of ground in Poland area.
